UNITED STATES PATENT OFFICE,

IJOUIS O. DHOMERGUE, OF BROOKLYN, NEW YORK, ASSIGNOR OF THREE- FOURTHS TO JOHN J. BRYERS, OF SAME PLACE, LOUIS IV. FROST, OF JAMAICA, NEJV YORK, AND HENRY M. THOMPSON.

BICYCLE-RAI LROADQ SPECIFICATION forming part of Letters Patent No. 456,215, dated July 21, 1891.

Application filed-February 12. 1891. Serial No. 381,203. (No model.)

novel devices, hereinafter described, for guiding or balancing the cars running on the single rail.

In the accompanying drawings, Figure I represents an end View of two cars in position on a road embodying myinvention with the rails in vertical cross-section. Fig. II represents a plan or top view thereof with the top guide-rails in horizontal section. Fig. III represents a bottom view of the car. Fig. IV representsa perspective view'of a guide-plate for attachment to the roof of the car.

Similar letters of reference indicate similar parts.

The letter A indicates the road-bed; B, a series of walls built thereon, and C an arch surmounting the walls at the intersection of streets, the whole forming a viaduct-road. On a surface road or elevated road, however, suitable posts or columns are used in lieu of the walls B and suitable girders in lieu of the arch O, the girders being located at proper distances apart from each other.

The letter (2 indicates a bed-rail for receiving the bearing-wheels of each of the cars, and ff and g g two sets of guide-rails, the guide-rails ff being above either car and, like the bed-rail c, in the central line of traction, while the guide-rails g g are at the opposite sides of either car approximately in the plane of the car roof.

2' '11 are the bearing-Wheels of either car fitted to the bed-rail e, the same being in vertical position.

j j are guide-wheels located on the top of either car in horizontal position for engaging the top guide-rails f f, and 70 7e are lugs or flanges located on the sides of either car, also in horizontal position for engaging the side guide-rails g' The bed-rail 6 may be either headed or grooved, the bearing-wheels 1? 11 being shaped to conform therewith, and when a grooved rail is used either car may be equipped with a suitable plow for removing dirt or other obstacles therefrom. The top guide-rails ff consist of strips of angle-iron, one side of each of which is fastened to the arch C or its substitute girders, so as to bring the other side thereof into a vertical position, such vertical side being left plain to engage the plain periphery of either guide-wl1eelj,wl1ile the side guide-rails g g are grooved to receive the guide-flanges 7c 7c, and are fastened to the proper parts of the walls B or their substitute columns.

The guide-wheels jj are usually keyed to shafts which are set into socke'tson the carroof, and each of said wheels may be provided with an oil-cu p for lubricating its shaft. Said guide-wheels 7' j, moreover, are placed diagonally opposite each other, as more clearly shown in Fig. II, in order to reduce the width of space between the top guide-rails. The side flanges 7c is may be properly secured to the opposite sides of either car, as shown in Figs. I, II, and III, or they may be formed by the ends of aplate 70, Fig. IV, by mounting this plate on the car-roof, with its said ends projecting therefrom.

When my invention is applied to a viaductroad, both the top guide-rails f f and side guide-rails g g are used; but neither set of said rails is continuous -that is to say, the top guide-rails are used only on the curves of the road to receive the guide-wheelsjj at those points, while the side guide-rails are used only on straight portions of the road to receive the guide-flanges 7c 70 along such portions thereof. When, however, my invention is applied to a surface road-or elevated road, either the top guide-rails ff or side guiderails g g may be omitted.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. A bicycle-railroad having a bed-rail and a set of top guide-rails, in combination with a car having bearing-wheels to engage the bed-rail and guide-wheels to travel between the guiderails and engage the same, said latter guide-Wheels secured to the car diago- 5 nally opposite each other.

2. A bicycle-railroad having a bed-1*ail, top guide-rails, and side rails, in combination with a car having bearing-Wheels to engage the bed-rail, side flanges to engage the side guiderails, and guide-wheels arranged diagonally 1o opposite each other to travel between the top guide-rails and engage the inner faces of the same.
